The COMPONENT_NAME component of a vector is the amount it moves DIRECTION.

style({ stroke: BLACK }); line([AOX + AX, AOY], [AOX + AX, AOY + AY], { arrows: "->" }); style({ strokeDasharray: "."}); line([AOX, AOY], [AOX + AX, AOY]);
style({ stroke: BLACK }); line([AOX, AOY + AY], [AOX + AX, AOY + AY], { arrows: "->" }); style({ strokeDasharray: "."}); line([AOX, AOY], [AOX, AOY + AY]);

Vector \vec a starts at COMPONENT_NAME = [AOX, AOY][COMPONENT] and ends at COMPONENT_NAME = [AOX + AX, AOY + AY][COMPONENT].

Therefore, vector \vec a moves DIRECTION [AX, AY][COMPONENT] units.

Therefore, vector \vec a moves DIRECTION 1 unit.

The only other vector that moves DIRECTION [AX, AY][COMPONENT] units is \vec ANSL.

The only other vector that moves DIRECTION 1 unit is \vec ANSL.
